LONDON - Palace officials say Prince William and the former Kate Middleton's first baby is due in July and that her condition is improving.

The Duchess of Cambridge, as she is formally known, had been hospitalized earlier in her pregnancy for acute morning sickness.

Officials said Monday she is feeling better. She made a rare public appearance last week and appeared to be healthy.

The infant would be third in line for the British throne.  The Queen has said if the baby is a girl, she will be given the title of Princess.
